 All right. Hello everyone. This is a video write up for the challenge find me ASAP from hack on 2018 challenge Prompt is what does this look like and we're given this file to download so we can copy this download it to our Directory and we have this find me dot-text file that we can cat out check out the contents and it is a lot of numbers So I notice in these that there are a lot of values that are 100 or a little bit below that a little bit above That so we've got some stuff that is essentially from 0 to 255 We can safely assume so that means that it's in the ASCII range So we can try and figure out what all these things are as ASCII I'm gonna go ahead and do this as a little Python script This can be our get flag and we'll go ahead and open up that prompt here Find me dot-text I'll set that as the handle I'll make sure to close that for good practice. I will mistype everything that I write just for good practice and Let's actually go ahead and display all of that on the screen Find me dot-text looks like it doesn't have an underscore perfect. Okay, let's go ahead and split these up So now we just have them all as numbers. Let's go ahead and use some list comprehension to convert them into integers I'll use int x For x in c dot split so now we have them all as numbers and now we can convert them to characters Just like that and then we can go ahead and join them So we have them all as one long string so we have Blah blah blah a lot of nonsense. Okay, we can assume that we've got the flag format in there though So let's go ahead and find with regular expressions Let's use re dot find all and we know the flag format so far is dark code with whatever we want in there and We want to track that down with what we're looking at so we can find it just like that ASCII and grep Get just the very last bit there and that is our simple get flag script. We have found the flag just like that Let's go ahead and mark this challenge as complete make this flag executable and Just like that. We are done with that challenge.
